Shaped offset quadrature phase-shift keying
WebbEach OAM mode carries a 100-Gbit/s quadrature phase-shift keying signal (aggregate 400 Gbit/s) on a single wavelength channel ( $\lambda \sim 1550$ nm) and is transmitted for a 2-km link. The calculated received power and inter-channel crosstalk of an OAM–MIMO/SMM signal fluctuate by 4.5 −6 dB, respectively.

Webb6 apr. 2011 · Offset Quadrature Phase-shift keying (QPSK) is also known as Staggered quadrature phase-shift keying (SQPSK). With typical QPSK you can see a 180° phase change from one symbol to the next and after filtering the incoming signal there can be large variations in the amplitude.
